Answer:
The percent error in Isabel's measurement is <u>12.5%</u>.
Step-by-step explanation:
Given:
Isabel thinks she has space for a 45 inch wide bookcase it turns out she only has space for a 40 inch wide bookcase.
Now, to find the percent error in Isabel's measurement.
Measurement she thinks = 45 inch.
The actual measurement = 40 inch.
<u><em>So, the error in measurement</em></u> = 
Now, to get the percent error of the measurement:
Therefore, the percent error in Isabel's measurement is 12.5%.
Answer:
-4/15
Step-by-step explanation:
2/5-4/6=2/5-2/3=6/15-10/15=-4/15
Answer:
B: 5/13
Step-by-step explanation:
pythagoras theorem: a^2 + b^2 (sides) = c^2 (hypotenuse)
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = 5
sin = opp/hyp
sin 5/13
Hope this helps
Answer: 2200 yards
Step-by-step explanation:
First find the unit rate, 660/3 = 220
So, Owen can jog 220 yards in one minute.
220 times 10 to find how much Owen can jog in 10 minutes.
220*10 = 2200.
Answer:
A.
Step-by-step explanation:
Take a look at what happens when squaring either of these...
Notice a couple of patterns.
1. The last term has a positive coefficient. That rules out answer choices C and D.
2. The coefficient of the middle term is either 
. So what are <em>a</em> and <em>b</em>? <em>a</em> is the square root of the x^2 term and <em>b</em> is the square root of the y^2 term.
The middle coefficient needs to be either +30 or -30. The answer is choice A.
